About This Tool
Introduction
How fast am I running — and how long will a 10K or a marathon actually take? Trencada's free Running Pace Calculator answers all three directions: enter distance and time to get your pace, enter distance and pace to predict your finish time, or enter time and pace to find out how far you'd go. Every result shows pace in both min/km and min/mile plus speed in km/h and mph, so it works whether you train in kilometers or miles. Runs 100% in your browser — free forever, no account.

Frequently Asked Questions (FAQ)
- How is running pace calculated? Pace is time divided by distance. For example, 25:00 over 5 km = 5:00 per km. The tool converts automatically to min/mile and km/h/mph.
- What is a good 5K pace? That depends on your level — casual runners often run 6:00-8:00/km, while trained runners go under 4:30/km. Use the calculator to set your own targets.
- Can I use miles instead of kilometers? Yes — distance and pace both switch between km and miles.
- Does this tool store my data? No. Everything is computed in your browser; nothing is sent anywhere.
